Gostai isn't putting all its software under the Affero GPL. It also produces a suite of graphical programming tools for robotics called Gostai Studio, an RTC interface for Urbi called GostaiRTC, and the GostaiNet cloud computing architecture for robotics.

Perhaps the most interesting of these is GostaiNet, which allows a number of robots to be controlled remotely from a cloud cluster. All you need are robots equipped with camera, microphone and speaker, and a WiFi router, and you can build your own robot army to take over the living room.

Why go open source? To help create compatibility among robots, simply the creation of programs and behaviors, and to extend Urbi into mainstream computing, in parallel and event-driven applications with multiple agents.
